plane. Increase the control travel, as you become 
more familiar with the flight characteristics until 
loops take about 50 feet and knife edge can be 
maintained with 80% stick deflection. Final roll 
rate should be 300-360 degrees per second. 
 

If you have followed the procedures in this 
Manuel you will now be rewarded with one of the 
finest flying sport models available. All primary 
aerobatic maneuvers are at your fingertips and 
the aircraft will perform them with ease.
